“…If the condyle is in an anterior position in relation to the mandibular fossa, such as in the open-mouth position, its venous plexus will be distended and visible as hyperintense on fat-suppressed T2-weighted images and as intense enhancement on postcontrast T1-weighted images, and should not be mistaken for enhancing synovium or pannus (33,38). Some studies have shown a change in its signal intensity in patients with TMJ pain compared with healthy subjects (47). However, it has no diagnostic or prognostic value in children with JIA.…”

MR Imaging of the Temporomandibular Joint in Juvenile Idiopathic Arthritis: Technique and Findings

The term juvenile idiopathic arthritis (JIA) encompasses a group of arthritides of unknown cause that begin before 16 years of age and last for at least 6 weeks. Temporomandibular joint (TMJ) involvement has been described in up to 87% of children with JIA and has been associated with all JIA subtypes. TMJ involvement is difficult to detect clinically. In one study, 71% of JIA patients with active TMJ synovitis were asymptomatic and 63% had normal physical examination results. Moreover, the main growth center of the mandible is located in the condyle, separated from the joint space by only a thin layer of fibrocartilage. This makes mandibular growth vulnerable to arthritic changes, eventually resulting in facial asymmetry and retrognathia. Therefore, early detection and treatment of TMJ arthritis are paramount to preserving motility and preventing deformity. As clinical symptoms and physical examination results are not good markers of TMJ involvement, imaging plays a key role in diagnosis and treatment monitoring. Magnetic resonance imaging is the technique of choice for the study of TMJ arthritis. It has the advantages of displaying both soft tissue and bone, is the most sensitive technique for detecting acute synovitis, and is the only one able to demonstrate bone marrow edema. In addition, it allows the assessment of changes to the joint over time and evaluation of the effectiveness of therapeutic interventions. RSNA, 2017.

“…Disc displacements may be partial or complete, depending on their extension. Trauma, anatomy of TMJ, bruxism, stress, masticatory muscle contracture, and abnormal dental occlusion may lead to elongation of the disc ligaments and indirectly to disc displacements and excessive load within temporomandibular joints and retrodiscal tissues [ 7 , 15 – 19 ].…”

“…The use of ARS in the treatment of disc displacement plays an important role, due to TMJ tissue unloading including retrodiscal tissues and insertions of selected masticatory muscles to articular discs [ 10 , 19 , 20 ]. The occlusal splint therapy which was carried out by the authors with the use of ARS was dependent on the results of a positive mandible protrusion test, resulting in the disappearance of the noise(s) during mouth opening from the protrusive incisal position of the mandible.…”

Background and Objective Intra-articular temporomandibular disorders are often related to pain in the area of the temporomandibular joint, ear, and temple. The aim of the study was to investigate the efficiency of anterior repositioning splints in decreasing pain related to temporomandibular joint disc displacement with reduction. Methods The research material consisted of 112 patients, aged 24 to 45 years, of both genders, who reported for treatment at the Consulting Room of Temporomandibular Joint Dysfunctions at the Jagiellonian University in Cracow between 2014 and 2016 due to pain in the area of the temporomandibular joint(s) and noise(s) of temporomandibular joint(s) present during jaw movements with comorbid contracture of masticatory muscles. Subjects were examined according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) protocol and, after diagnosis of painful disc displacement with reduction and masticatory muscle contracture, they were assigned randomly to either the study or control groups (56 patients in each). In the study group, we used an anterior repositioning splint on the full lower arch for about 20 hours usage over a 4-month period. In the control group, a noninvasive therapy was applied using a biostimulation laser over 12 sessions performed every second day on the area of both temporomandibular joints with mouth open and while performing muscle self-exercises with a dominant protrusive position of the mandible. Pain intensity was evaluated using the Verbal Numerical Rating Scale (VNRS) immediately before the treatment and then after 4 and 16 weeks. The obtained data were analyzed using the Mann–Whitney U test (p ≤ 0.005). Results The VNRS values reported during the final examination for the study group were significantly lower than for the control group (p=0.0004). Conclusions The anterior repositioning splint is an efficient tool in decreasing pain related to disc displacement with reduction. This trial is registered with Clinicaltrials.gov NCT03057262.

“…Heretofore, temporomandibular disorders (TMD) have been primarily perceived as functional disorders occurring in the masticatory system that are not accompanied by morphological changes. The use of advanced visualization technics, for instance, the MRI, has proved that TMDs also include pathological anatomical alterations of temporomandibular joints, as well as the surrounding craniofacial structures and masticatory muscles [ 1 , 2 , 3 , 4 , 5 ]. It is a common dental disease affecting an increasing number of people in the population.…”

“…TMDs’ etiology is multifactorial. The main symptoms are masticatory muscle pain and/or temporomandibular joint (TMJ) pain, and a clicking sound in joints, resulting from the pathological displacement of the articular disc with reduction or limitation of the jaw opening range [ 3 , 4 , 6 , 7 ].…”

Background: Disorders of the masticatory muscles and temporomandibular joints as well as the surrounding craniofacial structures are called temporomandibular disorders. These are dental diseases affecting an increasing number of people with a multifactorial etiology. Noninvasive ultrasonography imaging of temporomandibular joints was performed to obtain more detailed information on joint pathologies. Material and Methods: The aim of the study was to assess the influence of ultrasound examinations of the temporomandibular joints on the diagnosis and treatment planning in patients with temporomandibular disorders. The study included 110 patients examined with the use of the Research Diagnostic Criteria for Temporomandibular Disorders questionnaire, axis I and II, after which the initial treatment plan was created. All patients underwent an ultrasound examination of the temporomandibular joints. Results: The results reveal numerous morphological changes within the joint structures in all treatment groups. Comparative statistical analyses of symptoms were performed between study groups. Conclusions: The number of pathologies in the myofascial pain group was much higher than expected and required introduction of additional treatment procedures. Further studies confirming these results and the effectiveness of ultrasound diagnostic of temporomandibular disorders are recommended.
